still, a 6.2L or 454 DI engine would be INSANE!!! i'm thinking something like 800-1000HP N/A at the crank for a DI 454.
Doesn't exactly scale like that, but a 454 DI motor would be very impressive. Who knows if we will ever see something that big with fuel ecomomy regulations. Maybe we'll see a pickup with that in it???

I'm digging this thread, as I own the V-6 LFX.
Seriously though, the 60 degree DOHC DI engine is really a lot more than the 90 degree OHV SS V-8 with 2 cylinders chopped off. Ford did that with its modular motors, it saved them money but was not that spectacular, the engine size/HP ratio was pretty linear as I recall.
BUT what about a 4.6-5.3 liter V-6 LFX? That would be pretty exciting I think if they get the cylinder bore/stroke length right. What I am really impressed with the LFX motor is the flat torque curve, and "area under the curve". It almost reaches peak torque at a very low rpm. Torque makes the car easy and fun to drive around town, and we still have that magic 4500-6800 things get exciting HP range. I really dig this car. That said, if I won the lottery an SS or more likely ZL1 would be in the driveway tomorrow. My daughter could have my car, the wife an SS and a ZL1 for me. Also, without a manual I would not like the car as much. The manual is a key part of my driving experience.

LFX is not the average V6

well, if the current chevy 454 motor makes 650HP, a DI version making 800HP doesn't sound so out of reach to me...but then again, i'm pretty sure the particular motor on the website i was checking out had porting and other mods done to it.

back on topic, I LOVE my LFX engine in my camaro. i like being able to give it a bit of throttle at 2K RPMs and being able to accelerate quickly. in my mazda 3, unless you were at 4K+ RPMs, you weren't able to accelerate fast at all, and even at the peak power, it's still nothing compared to what i get in the camaro.
